Recently, due to work needs, I hope to make a comprehensive summary of the considerations related to SQL Server database performance optimization. After searching online, I found manyArticleSome of them list hundreds of entries, but you can see that there are a lot of seemingly incorrect or outdated information (which may be applicable to versions earlier than SQL

This example uses the same installation file, both of which are 2008R2 (OS and SQL) and are not updated online. Therefore, the version and Patch are basically consistent. If it is a formal environment, you need to consider that

impossible to design a system completely according to the standardization. Unless the system is very small, it is necessary to add redundancy in a planned manner after the standardization design.
Redundancy can be a redundant database, a redundant table, or a redundant field. redundancy at different granularities can play different roles.
Redundancy can be increased for programming convenience or for performance improvement. From a performance perspective, redundant databases can distribute
To operate SQL server data over the past two days, you need to set the time, minute, and second of a date field, that is, '2017-11-07 16:41:35. the 033 'is changed to '2017-11-07 00:00:00', so I checked the SQL syntax for datetime-type operations on the Internet and found th

This approach and Method 2 is very much the same, do not say more.Some trace flags that may be required in a production environment
Trace Flag 610Reduce the amount of log production. If you use a lot of the basic best practice for the log, such as only a log file, a proper number of VLF, separate storage, or if you can't mitigate the log too large, consider using the trace tag.

In SQL Server 2005, there is a table TestDatetime, where the data type of the Dates field is datetime. If you see a table record, what do you first think?

When you see this data, do you think this design is a waste of storage space and makes the index of this column increase, making the query slower, you also want to use some other data types to replace this datetime?
